1.11.0 Allow running SQL against each table individually.

For the cases when the input files are combined and their schema is not consistent, CSV Cruncher still can be useful by running the SQL against each of these schema versions.

However, that prevents CSV Cruncher to treat all files as sources to the same table, therefore multiple tables are created, like, foo_1, foo_2 etc, one for each schema version (columns combination).

This release implements this feature.
It also needed a major refactoring.
